Electrochromic Devices Using a Li2O-CeO2-SiO2 Ion Conductor

    Research output: Contribution to conferencePaper


    Electrochromic devices using a new lithium ion conductor based on the Li2O-CeO2-SiO2 system have been fabricated and tested. The system exhibits a high transparency (near 90% in the visible and near infrared range), fast ion-mobility, and good durability. Various preparation parameters have been investigated to improve the ionic conductivity and stability of the film. Electrochromic devices basedon the new ion conductor were prepared and tested. The devices had a structure of SnO2/LixWO3/Ion Conductor/V2O5/Au. When operated at plus-minus 3 V, the transmittance (at 670 nm) of the device can be switched between 28% and 8% in 10 seconds.
